STORM-SASHA PASTE-N ER.

SPECIFICATION forming part of Letters Patent No. 700,706, datedMay 20, 1902. Application filed October 23,1900. Serial No. 34,050. (No model.)

To all whom it may concern:

Be it known that I, EDWARD O. QUIMBY, of Minneapolis, I-Iennepin county, Minnesota, have invented certain new and useful Improvements in Storm-Sash Fasteners,of which the following is a specification.

The invention relates to storm -sash fasteners.

The primary object of the invention is to provide a fastening device which when the storm-sash is pushed open will automatically lock it in an open position and when the sash is closed will draw it in snugly to its seat within the window-frame. v

A further object is to provide a fastening device which will securely hold the sash in an open position and prevent shaking or rattling of the same.

A further object is to provide improved means for locking the sash when closed to prevent its accidental opening.

A further object is to provide a fastener that will not wear the sash.

A further object is to provide a fastener of simple and inexpensive construction, though strong and durable; and a still further object is to provide a fastener that can be easily attached to a storm-sash and window-frame and permit the ready attachment and removal of the sash.

Other objects will appear from ing detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described, and particularly pointed out in the claim.

In the accompanying drawings, forming part of this specification, Figure 1 is a vertical section in perspective of a window-frame and storm-sash with my invention attached thereto. Fig. 2 is a similarview showing the stormsash open. Fig. 3 shows a slightly-modified construction of fastener. Fig. 4 is a vertical section in perspective illustrating a modified form of fastener withthe-storm-sash closed. Fig. 5 is a similar view with the storm-sash open. Fig. 6 is a detail of the'fastener shown in Figs. 1 and 2. Figs. 7, 8, and 9 are details of modified forms of fastener-arms.

the follow In the drawings, 2 represents a window frame of ordinary or preferred construction, the usual window sash and stops, for the sake of clearness, being omitted.

3 represents a storm-sash hinged to the top of the window-frame in any preferred manner and adapted when closed to engage the stop 4: within the window-frame and form a close joint therewith to exclude moisture and cold.

5 is an arm or member of spring material, preferably wire, provided aton'e end with a hook 6 and its opposite end with a laterally and upwardlyturned loop 7, The, arm 5 is pivotally secured onthe storm-sash by a clip 8, which permits the arm to swing vertically when the sash is opened and closed and engages the loop to flex the arm when it is raised during the opening of the sash. Upon the window-frame at a point nearly opposite the said clip I provide a fastener comprising, preferably, a plate 9, secured to the window-frame by screws or other suitable means andprovided with a flanged extension 10, having a longitudinal slot 11 to receive the hooked end of said arm and wherein said arm is freely slidable. A lug 12 is provided on the flange 10 and adapted to enter said loop when the sash is nearly closed and having a curved or cam surface over which the loop slides. To close the sash, the operator raises the arm, disengaging its hook from the'fastenor and allowing the arm to slide in through the slot until the sash has nearly reached its seat. When the sash is nearly closed, the loop will drop over the end of the lug and the operator pressing down on the arm will turn it down against the edge of the flange 10, drawing the loop in over the cam-surfaced lug and the sash against its stop and locking the same until the arm is raised and the loop freed from the lug. After the arm is elevated the operator may pushopen, the sash, the arm sliding freely in the guiding-slot without further manipulation until theghook engaging the lower edge of the slot prevents further movement of the sash'in either direction. During the outward movement of the sash the arm is gradually swung on its pivot until the loop 7 strikes the clip, and then the continued movement of the sash flexes the arm and the tension thereof causes the hook to be held firmly in the lower end of the slot and prevents any shaking or rattling of the fastener or sash.

In Fig. 3 I have shown a slight modification, which consists in cutting away the edge of the flange 10 and forming a stud or projection 13 near the bottom of the plate 9 and providing therein a suitable groove wherein the arm 5 freely'slides, its hook portion engaging and pressing upon said stud when the sash is opened.

In Fig. 4 I have shown another form of fastener, in which the arm 14 is shown provided with a laterally-turned end 15 near the pivotal point of the arm and adapted to bear on a plate 16, provided beneath the clip 8. to prevent said end from wearing the sash. The inneror hooked end of the arm ltis preferably provided with a lateral extension 17 to be grasped by the operator to disengage the hook preparatory to closing the sash. On the windew-frame at a point substantially opposite the pivot of said arm I provide a hook 18, in which the arm 14 is adapted to slide and which is engaged by the hook on said arm when the sash is opened. This form of fastener is operated in substantially the same manner as those heretofore described. The operator raises the arm to unlock the fastener and then pushes open the sash and the fastener will automatically lock it without further manipulation. When the sash is being closed, the operator will turn the arm 14: down around the hook 18, and I prefer to provide a pin 19 in the frame between which and the sash the arm is pressed and held securely to prevent accidental opening of the sash.

I prefer to provide a bend in the arm 14 at the point where it is turned over the hook 18 to permit the pin 19 to be placed near the storm-sash stop and prevent the arm from interfering with the window-sash. When the arm is turned down to its locked position, the storm-sash will be drawn in and form a close joint with the stop on the window-frame.

It is sometimes desirable to regulate the distance that the storm-sash is opened, and I may therefore provide a series of hooks in the fastener-frame, as shown in Fig. 7.

In Fig. 8 I have shown another method of flexing the fastener-arm, which consists in providing a lug or shoulder 20 on the clip 15 in position to engage the arm and put it under tension when the storm-sash is being opened. When the fastener-arm is flexed in this way, I may dispense with the end 15, merely bending the pivoted end of the arm to prevent it from becoming disengaged from the clip. When the storm-sash is removed, the fastener-arm may be bent laterally to spring by the hooks or other fastening de vices on the window-frame.

A particular advantage of my improved fastener lies in the fact that as soon as the arm is elevated sufficiently to release the locking parts the operator may then push out on the stormsash and the arm will slide over or through its fastener and be automatically locked therein without any further manipulat-ion on the part of the operator.

I have shown the fastener arranged on one side only of the frame and sash; but it will be understood that by a simple reversal of the parts the device will be applicable for attachment toboth sides of the frame.

I prefer to employ spring-wire in the construction of the fastener-arm; but other material may be employed, if preferred. The sash-clip and the window-frame fastener may be made of suitably-stamped sheet metal or the parts may be cast, and with a few slight modifications in construction I may construct the frame and-sashfasteners of wire.

In Fig. 9 I have shown a modified means for flexing the straight arm, which consists in extending the backing-plate 16 out beyond the clip'15 on one side and forming thereon a lug 21 in position to engage the arm when it is elevated and flex the same during the opening of the storm-sash.

In various ways the parts of the fastener herein shown andsdescribed may be modified by any one skilled in the art without departing from my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent A storm-sash fastener comprising a plate to be secured upon the window-frame, and provided with a stud and a lug having an outwardly-turned cam-face, in combination,with a spring-arm that slides automatically upon said stud when the sash is pushed open and having a hook at one end and a loop at the other and pivoted at an intermediate point upon the sash, said hook engaging said stud and said loop engaging the sash and flexing said arm when the sash is open to hold the hook firmly upon said stud, and said loop being adapted to receive said lug and slide over its cam-face and draw the sash to its seat when said arm is drawn in and turned down. over said stud to close the sash, substantially as described.

In witness whereof I have hereunto set my hand this 19th day of October, 1900.

EDWARD C. QUIMBY.
